This was first noticed in the Wikidata home page, which uses an SVG file with labels localized into multiple languages. For example, https://www.wikidata.org/wiki/Wikidata:Main_Page?uselang=pt is showing the English labels, even though the Portuguese labels are available (and working) in https://commons.wikimedia.org/w/index.php?title=File:Wikidata_nodes_in_white.svg&lang=pt.
This is not exclusive to Wikidata: I can reproduce the issue also on ptwiki: pt:User:Waldyrious/Testes.
Steps to replicate the issue (include links if applicable):
What happens?:
- The banner image shows text labels in English.
What should have happened instead?:
- The labels in the banner image should be localized, as seen here.
